中药溪黄草药用成分复杂多样,有效成分尚不明确,且分子水平相关研究十分薄弱.因此,构建溪黄草转录组数据库,以生物信息学手段进行分析,可为中药溪黄草药物的研究开发利用奠定基础.本研究利用高通量测序平台Illu-mina 构建了两种常用溪黄草基源植物溪黄草和线纹香茶菜的转录组数据库,并进行了比较分析.两种溪黄草分别获得了 144 650 个和 103 221 个 Contigs,N50 值分别为 1 400 bp 和 1 516 bp.这些 Contigs 聚集成 107 777 个和 68 220 个Unigenes,其功能注释分析以鉴定有效药物成分的基因为主.整个转录组数据中分别有14 138个和11 756个EST-SSR基因序列.本研究不仅快速地解读了溪黄草整体的基因组信息,还为挖掘相关的功能基因、阐明活性成分的生物合成及其调控机制、评估种质资源和发现隐藏的药用部位提供重要的科学依据.
Construction and Comparative Analysis of Transcriptome Data of Two Kinds of Isodon serra
The medicinal components of Isodon serra were complex and diverse,the effective compo-nents were not clear,and the related research at molecular level was very weak.Therefore,construc-ting the transcriptome database and analyzing it by bioinformatics means could lay a foundation for the research,development and utilization of traditional Chinese medicine.In this study,transcriptome databases of two commonly used Isodon serra source plants and Isodon lophanthoides was conducted,using high-throughput sequencing platform Ilumina,and comparative analysis were conducted.A total of 144 650 Contigs and 103 221 Contigs were obtained from the two species,with N50 values of 1 400 bp and 1 516 bp,respectively.These Contigs were aggregated into 107 777 and 68 220 Unigenes,whose functional annotation analysis focused on the identification of genes and active drug ingredients.There were 14 138 and 11 756 EST-SSR gene sequences in the transcriptome data,respectively.This study not only quickly interpretted the whole genomic information of Isodon serra,but also provided important scientific basis for mining related functional genes,elucidating biosynthesis of active com-ponents and their regulatory mechanisms,evaluating germplasm resources and discovering hidden medicinal sites.
